“Targeted Therapy”Chemotherapy

Checkpoint ImmunotherapyGenomics‐driven TKIs:

‐EGFR‐ALK‐ROS1

Anti‐PD‐1 and PD‐L1 

(Anti‐CTLA‐4)?

What are the available “Tools” to facilitate Individualized Therapy in advanced stage NSCLC?

The Questions: How do we optimize therapy in individual patients? How do we account for tumor evolution over time and after targeted therapy?

How do we best integrate new diagnostic testing platforms for targeted therapy or immunotherapy to achieve optimal results? (Next Gen Sequencing [NGS] in

tissue or cell free[cf]DNA in plasma)

• Cancer cells have mutations that make them recognizable by the immune system (neo‐antigens)

• Theoretically, the higher the mutational load (e.g. through smoking), the greater the immune recognition

• Cancer cells can evade immune surveillance by expressing proteins such as PD‐L1 (a potential biomarker)

Perspective on CheckMate Phase III Trials

Trial 017: Squamous Cell Carcinoma

Trial 057: Non-Squamous Cell Carcinoma

Two positive randomized phase III trials of nivolumab vs. docetaxel,

but very different “Kinetics of Survival Curves”

“Kinetics of Survival Curves (OS)”Trial 017 SQ: Early & continuous separation

Trial 057 Non-SQ: Cross-over but subsequent separation

“ If you try to do it in one bite, you willchoke on it”

There is no single solution to defeating Lung Cancer.

Like the elephant, it will take many bites.
